I'm a long time golfer who has just gotten into tennis the last couple years. There are a lot of similarities between the two swings, but there is one move in tennis that will kill your golf game: flipping the wrist at impact.
You are right about the shoulder turn: in tennis it is quite a bit more horizontal than in golf, which requires that your right shoulder go down and toward the ball.
